Transportable wireless ATEX area gas detector (pumped) with sensors for LEL Methane, Oxygen, Hydrogen Sulphide and Carbon Monoxide.  Ideal for area surveillance, or in applications where a fixed system does not need to be permenantly installed.

Teledyne Oldham BM25 (LEL/O2/H2S/CO) Pumped Transportable Gas Detector

Teledyne Oldham BM25 Wireless (LEL/O2/H2S/O2) Pumped Transportable Gas Detector

The BM25 is a transportable gas detector, designed to simultaneously detect up to five gases.  This particular model is wireless, pumped and has sensors for LEL Methane, Hydrogen Sulphide, Carbon Monoxide and Oxygen.  There are also sensors available for other combustible gases, sulphur dioxide, ozone and many others.  

The BM25 gas detector can be likened to a fixed system area monitor and is ideal for harsh environments and applications where temporary work is being carried out, team protection, area surveillance or where it is not possible for a fixed monitoring system to be permanently installed.  It’s designed to ‘stand up’, so the feet allow it to be placed on any flat surface.  The display will simultaneously show all gases monitored so any gas readings can be seen immediately.

There are added benefits to the wireless version of the BM25 transportable gas detector.  The remote power supply is intrinsically safe, so ensures that there is continuous operation in hazardous environments and its line-of-sight range is around 1,000mtrs.  The BM25 has a built-in output relay which allows the unit to be connected to remote alarm devices in applications such as rig overhauls, fence-line surveillance, refineries, and pharmaceutical productions.  A mesh network can be created to provide wide coverage and a higher tolerance of faults.  When used in conjunction with the MX40 controller up to 32 measurements can be displayed at a centralised location in real time.  The MX40 can communicate with other connected BM25s, should an alarm go off.

Key Features

  • Clear LCD display with a backlight for dark conditions
  • Datalogging capacity can hold up to 200,000 measurements
  • Double alarm system – audible (103db @ 1mtr) and 360° ultrabright LED beacon
  • Recharge Time – typically 4.5 hrs with a runtime of up to 170 hours operating time or 135 hours in wireless mode (on NiMH battery)
